I've got the correct bolt face in a single shot BR rifle so I'm debating within on doing 22N vs 223AI. I'll have either one throated out far for the 80's on up to the new 95SMK and will do a 6.5 twist heavy and long barrel. Anybody done a 22N similar to what I have in mind? I know the cartridge doesn't have the strongest brass and rims tend to get torn up using the AR platform but with bullets seated way out in a single shot I'd think one could get enough extra fps to make it worthwhile over 223AI, yes or no???
